Yeah it spreads very fast, the problem is that you won't know until you feel any pain or visit a dentist.

I certainly agree.

They won't magically disappear, so cavities must be treated the moment they're Identified.

correct, I think I resisted visiting dentist at first, then after 1 week when I finally visited, he told me that one should never wait as soon as they see a problem because it  may cause severe damage to one's mouth. Luckily I got cured.
Thanks

Absolutely.

A friend of mine at work chipped her tooth and given It wasn't hurting at the time, she left It as Is for around a year. All of a sudden, the pain hit like a ton of bricks and she was on the phone to every dentist who had the first available appointment. The equation Is pretty simple- get It looked at there and then.
